digitally programma- ble Phase locked loop With a 4 MHz quartz crystal, the PLL permits precise set- ting of the frequency of the Tuner Oscillator up to 1024 MHz in increments of 31. 25, 50, 62. 5 or 166. 7 kHz. The tuning process is controlled by a micropro- 2 cessor via an I C bus. The device has three output ports. A flag is set when the 2 loop is locked. It CAN be read by the processor via the I C bus.
